We describe a project in the field of computational electrocardiology which requires visualization of complex, three-dimensional geometry and electric potential and current fields. Starting from magnetic resonance images from a healthy subject, we constructed a multisurfaced model of the human thorax, which we used as the basis for computational studies relating potential distributions measured from the surface of the heart to potentials and currents throughout the volume of the thorax (a form of the forward problem in electrocardiography). Driven by the lack of adequate visualization software, we developed both interactive and batch-mode graphics programs to view, manipulate, and interactively edit the model geometry and present our results.
